Community is an extremely important thing. Having many people capable of performing various functions in harmony together makes life easier. What I know how to do may be something you aren't capable of doing. So I can perform it for you. What you know how to do may be something I am incapable of doing. So you can perform it for me.
Having multiple people performing the same thing for others can create a healthy competition and can help those performing to step up their game in order to make sure that the absolute best service is being performed. In some instances, like in music, it's even better to have multiple people doing it because it creates a variety.
So I say that you can't spell community without "u" "n" "i".
You can't have a community without you and I.
With that in mind, let's all keep in mind that the world will not revolve around one person, ever. It is as important to support those around you as it is for those around you to support you. Reciprocity is a key to a healthy community. Respect for variety is a key to a healthy community. Respect for each other is a key to a healthy community.
Unity is better than division, always.
